Nearly an hour of lapping, is this what a new DMT 325 should look like?
My first DMT 325 arrived the mail the other day, and I have sharpened quite a few kitchen knives off of it to break it in. I started lapping the norton 1000 side of my combo hone that came in, and here are the end results of both -

The first picture is of the DMT, and as I hope you can see there is a darker area on most of the hone. The lighter areas towards the outside of the hone seem to have more bite to them. My thought is that there is just less grit where it is darker given that I have been doing circles on the Norton 1000. I am kind of surprised though to see that dramatic of a difference. Is that pretty normal?
The second picture is of the Norton 1000, and it shows some feint/shallow but present scratch marks in a circular pattern. It looks pretty similar to the thread posted the other day about a new DMT 325 being used straight out of the box onto a hone. As I mentioned, I ran quite a few kitchen knives over the DMT before I tried using it on the hone. Do the scratches (if you can see them) mean that I need to break out the knives again for the DMT?
About thirty minutes into the initial lapping, I took a picture of the hone with the DMT to show the degree of flatness

I was expecting to lap the Norton for a little bit of time. I'm over an hour into it and though it isn't that drastic anymore, I have the feeling I have a bit more to do. Should this much lapping be required for the first run?
Cheers
